1过去进行时1.概念：表示过去某段时间或某一时刻正在发生或进行的行为或动作。2.时间状语：atthistimeyesterday,atthattime或以when引导的谓语动词是一般过去时的时间状语等。yesterday,last,ago,before,in+年或月,on+日,justnow(或者amomentago)3.基本结构：was/were+doing4.否定形式：was/were+not+doing.5.一般疑问句：把was或were放于句首。主要表示在过去的某个时间点上正在发生、进行的动作。由于它的定义是表示在过去的某个时间点上正在发生、进行的动作，所以，句子常带有一个表示“过去某个时间点”的状语。这个状语可能是短语，词组，或是一个从句。也可能是通过上下文来表达这层意思。过去进行时主要用于下面的情景中：1）表示在过去某时刻正在进行的动作，例如：Atthismomentyesterday,Iwaspackingforcamp.昨天这个时候，我正在收拾东西去露营。WhenIcametoseeherlasttime,shewaswritinganarticle.上次我来看她的时候，她正在写一篇文章。Whatwereyoudoingateightlastnight?昨晚八点钟你在做什么？2）用于故事的开头，交代故事发生的背景情况。过去进行时所描述的动作是“正在进行”，所以，在这种情景中用“过去进行时”可以给读者一种“动感”，从而能使文章更加生动活泼。例如：Onenight,hewastypinginhisstudy.Suddenly,amanbrokeintohishouseandcutofftheelectricity….一天晚上，他正在书房里打字。突然，一个人闯进屋来，切断了电源……3)（仅限少数动词）表示在过去的未来时间要发生的动作。例如：WhenNationalDaywascomingnear,theybegantomakeaplanfortheholiday.国庆节即将来临的时候，他们开始制订度假计划。ShetoldmethatshewasgoingtoHainanforherholiday.她告诉我她将去海南度假。Myfriendsaidtomethathewaslunchingwithoneofhiscustomersthatday.我朋友对我说，他今天要与他的一位客户一块儿吃午饭。Welefttherewhenit'sgettingdark.天快黑的时候，我们离开了那儿。6.用过去进行时表示现在，主要是为了使语气委婉、客气。如：Iwaswonderingifyoucouldgivemealift.我不知你能否让我搭一下车。Wewerehopingyouwouldstaywithus.我们很希望你能跟我们住在一起。Howmuchdidyouwanttospend,sir?先生，您打算花多少钱？注：一般过去时也有类似用法，但比较而言，用过去进行时显得更客气，更不肯定。2过去进行时练习题一、用动词的适当形式填空1.Whilewe__________(wait)forthebus,agirl__________(run)uptous.2.I__________(telephone)afriendwhenBob__________(come)in.3.Jim__________(jump)onthebusasit__________(move)away.4.We__________(test)thenewmachinewhentheelectricity________(go)off.5.She_____(notwant)tostayinbedwhiletheothers_____(all,work)inthefields.6.Whilemother________(put)Cathytobed,thedoorbell________(ring).7.AsI__________(walk)inthepark,it__________(begin)torain.8.Evenwhenshe___________(be)achildshe________________(already,think)ofbecomingaballerina(芭蕾舞演员).9.Itwasquitelateatnight.George__________(read)andAmy__________(ply)herneedlewhenthey__________(hear)aknockatthedoor.10.There__________(be)agrouproundthefirewhenthey__________(reach)it.Anoldwoman__________(sit)onthegroundnearthekettle;twosmallchildren__________(lie)nearher;adonkey__________(bend)hisheadoveratallgirl.11.I_____(have)mybreakfastathalfpastsixyesterdaymorning.12.Mary_____(go)overherlessonsfromsixtosevenlastnight.Johnandpeter____(do)thesamething.13.What_____you___(do)atthattime?We_____(watch)TV.14.Wasyourfatherathomeyesterdayevening?Yes,hewas.He_____(listen)totheradio.15.They_____(notmake)amodelshipwhenIsawhim.16._____they____(have)ameetingat4yesterdayafternoon?No,they_____.They_____(clean)theclassroom.17.______it______(rain)whenyouleftschool?Yes,it____.(No,it____)18.What_____yourfather_____(do)whenhewasyourage?19.Oneday,Edison_____(wait)foratraintoarrive,andsuddenlyalittleboyrantothetrack(轨道)toplay.20.HeaskedmeifI______(go)fishingthatafternoon.21.Thethreeofthemwereinahurrybecausetheirplane_____(leave)infiveminutes.22.Inaletter,johntoldusthathe_____(come)tochinanextmonth.23.Whenthebellrang,jenny_____(wait)inherseat.24.She_____(make)herdressthewholeafternoon.25.Whilemyfather____(look)throughtheeveningpaper,hesuddenly____acry.26.WhenI____(come)intheroom,he____(see)me,forhe____(read)something27.Whenwe_____(arrive)atthevillage,it_____(get)darkandit_____(rain)hard.28.I_____(know)you____(wait)formehere.29.Onedayalittlemonkey____(play)inatalltree.Amothercrocodile(鳄鱼)____(look)forfoodnearthebank.330.What____yourfather____(do)yesterdayevening?He____(study)attheeveningschool.31.Laterhisparentsfoundthathe_____(sit)onsomeeggs.32.Whenheknockedatthedoor,myaunt____(cook)33.Thestudents______(sing)and____(dance)happilyontheplaygroundatthattime.34.I____(write)aletterwhenthedoorbellrang.35.Wehadnoclassedatthattime.We____(plant)trees.二、选择题1.I______cookedamealwhenyou_____me.a.cooked,wereringingb.wascooking,rangc.wascooking,wereringingd.cooked,rang2.Hesaidhe_____todrawaplaneontheblackboardatthattime.a.triesb.triedc.wastryingd.willtry3.Whileshe______TV,she______asoundoutsidetheroom.a.waswatching,washearingb.watched,washearingc.watched,heardd.waswatching,heard4.They_____afootballgamefrom7to9lastnight.a.werewatchingb.watchc.watchedd.arewatching5.Whatbook____you______whenI____youatfouryesterdayafternoon?a.did,read,wasseeingb.did,read,sawc.were,reading,sawd.were,reading,wasseeing6.ItwasFridayevening.MrandMrs.Green_____readytoflytoEngland.a.aregettingb.getc.weregettingd.got7.LeiFeng_____always_____ofotherswhenhe______inthearmy.a.is,thinking,wasb.was,thinking,isc.did,think,isd.was,thinking,was8.Agirl______mypenfalloffthetablewhenshe_____me.a.saw,passedb.wasseeing,passedc.wasseeing,passedd.wasseeing,waspassing9.We____fortomattenlastSunday.Heoftenkeptus______.a.werewaiting,waitingb.werewaiting,waitc.waited,waitingd.waited,wait10.He____hisfatheronthefarmthewholeafternoonlastSaturday.a.helpsb.wouldhelpc.washelpingd.ishelping11.Whilemother_______somewashing,I_____akiteforKate.a.did,madeb.wasdoing,madec.wasdoing,wasmakingd.did,wasmaking12._______youangrythen?they______toomuchnoise.a.are,weremakingb.were,weremakingc.are,maded.were,made13.He____somecookinga
